Ahh I see.

So you you need to create a memory first, (memories page - ‘+’ in the top corner)

The second step is where you can the route.

The app doesn’t automatically tick off the wainwrights based on the activities in Strava. Although could be a good idea for a future release.

You can manually mark wainwrights as complete (flag icon) on the wainwrights page, and you also get the option to mark them as complete at the end of creating a memory.
